Title: Very-low-frequency high-voltage power supply
Inventor: ASAI HIROBUMI
IPC: H02M7/155
Filed: 1988-02-26
Abstract: PURPOSE:To make a high voltage change over switching circuit unnecessary by using each pair of modulators, power amplifiers, highfrequency transformers, and voltage doubler half-wave rectifiers. CONSTITUTION:A low-frequency high-voltage power supply is composed of a verylow-frequency oscillator, a carrier oscillator, positive and negative half- wave modulators, power amplifiers PA, high-frequency step-up transformers T, voltage doubler half-wave rectifier circuits and others to supply power via smoothing capacitor CO and the like. Further, said smoothing capacitor CO is connected between respective output terminals of said rectifier circuits via short-circuit prevention and waveform composition resistances R respectively, and a negative feedback circuit to a low-frequency amplifier A is also provided at said power supply. Thus, a high-voltage waveform having the same frequency as and being similar to those of said low-frequency oscillator output can be obtained between smoothing capacitor terminals.

Title: Contact type keyboard for typewriter
Inventor: GASUTOONE FUAKO
IPC: H01H13/702
Filed: 1988-02-26
Abstract: PURPOSE: To reduce the size of a keyboard and to enhance reliability by causing a stopping element to project into a domed part. CONSTITUTION: Axial movement of an actuator 13 is caused at the press of a key 12, an outside ring 26 deforms outside and inside diaphragms 17, 18 when pressed, and an electrically conductive pellet 21 is engaged with an element 22 to produce a corresponding electric signal. Since a stopping element 27 takes the form of a circular ring, this device constantly gives a secure and stable state of engagement and contact between the element 27 and a surface 28. Since the peripheral diaphragm 17 and the inside diaphragm 18 adjoin to the stopping element 27 and have limited uniform thicknesses, both of the diaphragms can be deformed with a minimum amount of pressure when their respective keys 12 are pressed.  Therefore, the stopping element 27 taking the form of the circular ring can greatly reduce an overall outer size, simplify the shape of an actuator 13, and guarantee secure and stable stopping action.

Abstract: PURPOSE:To eliminate a voltage drop and noise and to protect a semiconductor pressure sensor from seawater, etc., by providing the semiconductor pressure sensor, a ship speed arithmetic means, and a display part such as a liquid crystal display part in the same housing. CONSTITUTION:A glass plate 14 for protection is fitted in the front surface of a front case 10 and a print panel 15, the liquid crystal display plate 16, a light guide plate 17 for illumination, and a reflecting plate 18 are fitted behind the glass plate 14. The semiconductor pressure sensor 21 as a speed detecting means is fitted to a rear case 11. Then the difference between pressure applied to a measurement pressure application part 22 and the atmospheric pressure strains the diaphragm of the pressure sensor 21 to cause variation in diffusion resistance value. The output voltage of the sensor 21 is supplied to a control circuit part 23 through a lead line. A circuit part 23 functions as a ship speed arithmetic means and processes the output voltage of the sensor 21 as prescribed to calculate a ship speed. Consequently, the signal line between the sensor 21, and speed arithmetic means and display part may be short, and the housing cuts off entering seawater, etc.

Filed: 1981-03-30
Abstract: PURPOSE:To improve the processing efficiency of addressing for a memory, by eliminating branch instructions from a program as much as possible to simplify the program and making the processing for discriminating whether conditions are satisfied or not unnecessary. CONSTITUTION:The input to a memory address register MAR 22 is supplied from a base memory address register BMAR23 or an adder 24. Switching and selection between them is dependent upon whether an address register selecting signal (a) is applied to the MAR22 or not. When an address register control signal (b) and the output signal of a comparator 26 are turned on together, the selecting signal (a) is sent to the MAR22 from an AND gate A1. The comparator 26 compares a condition code (c) and the code of an encoder 27 with each other and issues the output for the coincidence between them. A base memory address is set to the BMAR23. The adder 24 outputs the result of the addition between contents of the BMAR23 and a CMAR25 to the MAR22.
